add some unit test for property type inference

git-svn-id: https://svn.code.sf.net/p/jackcess/code/jackcess/trunk@871 f203690c-595d-4dc9-a70b-905162fa7fd2

TODO.txt

   - numeric data has embedded precision/scale, something else?  only last 8
     bytes is data?  implicit precision of 18 for "pure" numeric?  implicit
     precision of 15 for double-ish numeric?
+  - ***add unit tests
+  - ***ability to create calculated columns!
 
 - add properties on table/column creation
+  - add unit tests
 
 - calculated fields in queries? (2003+), w/ aliases?
